CORMET 9
All-positional flux cored wire
Product description Cormet 9 is an all-positional flux cored wire suitable for welding fixed pipework. Made using a high purity steel
sheath with a metal recovery of about 90% with respect to the wire.

Operating parameters Shielding gas: 80%Ar-20%CO2 at 20-25l/min. Proprietary gases may be used but argon should not exceed 80%.
The wire is also suitable for use with 100%CO2. (Note: for 100%CO2 shielding gas, voltage should be 1-2V
higher.)
Current: DC+ve ranges as below:

Packaging data Spools vacuum-sealed in barrier foil with cardboard carton: 1.2mm diameter 15kg
The as-packed shelf life is virtually indefinite.
Resistance to moisture absorption is high, but to maintain the high integrity of the wire surface and prevent any
possibility of porosity, it is advised that part-used spools are returned to polythene wrappers.
Where possible, preferred storage conditions are 60% RH max, 18°C min.
